PNG to ICO Converter — Convert an Image to an ICO Icon Free

Upload a square PNG (256 × 256 or larger), choose the ICO sizes you need (16, 32, 48, 64, 128, 256), and download a multi-resolution .ico file ready to drop into the root of your website as favicon.ico — recognised by every browser since Internet Explorer 6.

Windows desktop and shortcut icons traditionally include 16, 32, 48 and 256 pixel renditions in a single ICO so the OS can pick the right resolution per context. Modern Windows 11 prefers 256-pixel icons; older apps still need 32-pixel.

Yes. Upload SVG (which scales cleanly at every resolution), JPEG or WebP and the converter rasterises each requested ICO size from the original. SVG produces the sharpest results because every size is rendered fresh from vectors.

Yes. Transparent PNG, SVG and WebP sources keep their alpha channel in the ICO, so the icon blends cleanly into dark and light browser tabs, Windows themes and macOS dock backgrounds.

favicon.ico is a multi-resolution Windows icon recognised by every browser. Apple touch icons are 180 × 180 PNG files referenced by an HTML link tag, used by iOS and iPadOS when adding the site to the home screen. Most modern sites ship both.

Your logo is uploaded and handled under our Security policy. Service providers may process it only as needed to deliver the requested icon. Pixoate does not sell files or use them for model training. Retention follows the Security policy; a share link you explicitly create can be opened by anyone with the link without automatic expiration while Pixoate provides the sharing service. If you need a strictly offline workflow for an unreleased logo, use a desktop icon-editing tool.

"Single .ico" bundles every size you selected into one multi-resolution icon file — the standard choice for a website favicon.ico. "Separate (.zip)" instead exports one individual .ico per selected size, useful when a build pipeline or app packaging tool (Electron, Android, Windows installer) expects distinct icon files rather than one combined container.

Yes — Separate (.zip) mode only produces a ZIP when 2 or more sizes are selected; picking just one size in Separate mode downloads a single .ico instead, since zipping one file adds no value. Select at least two sizes if you specifically need the per-size ZIP output.

For a website favicon, keep the default sizes (16, 32, 48, 64, 128, 256) in Single .ico mode — one favicon.ico covers browser tabs, bookmarks and Windows shortcuts. For a native app icon set (iOS/Android/Electron), select all 8 available sizes and switch to Separate (.zip) so each resolution ships as its own file, matching what most app packaging tools expect.

The default selection (16, 32, 48, 64, 128, 256) covers the sizes browsers and Windows request most often, keeping the file small. Add 24×24 if you're targeting older Windows toolbar contexts, or 96×96 for some Linux desktop environments and higher-density app launchers — toggle any of the 8 available sizes on or off with a single click.

Sizes at or below 32 pixels are rendered with pixelated (nearest-neighbor) scaling in the 'Preview at each size' panel, which matches exactly how a real favicon looks in a tiny browser tab — smoothing it would make the preview misleadingly softer than the actual icon. Sizes above 32 pixels use normal smooth scaling since that's how they render in practice.

Pick the sizes you need — any of 16, 24, 32, 48, 64, 96, 128 and 256 pixels — and keep the bundle option selected to create one multi-resolution .ico file. Windows and browsers then pick the right size from the file automatically. Prefer separate files? Switch to one .ico per size, and two or more sizes are delivered together as a ZIP.

Yes. Upload any common image — PNG, JPG, WEBP, SVG, HEIC and more — preview the icon set and download the clean standard .ico without creating an account. Files are deleted automatically after conversion.

Yes — Pixoate supports batch and bulk processing. Switch to Batch mode, add up to 60 images on Premium or 200 on Pro, set your options once, and every image is processed with the same settings before you download a single ZIP. Bulk processing is a Premium feature; the output uses the same quality and settings as single mode.

Yes — with bulk processing you configure the settings a single time and they apply to every item in the batch — up to 60 images on Premium or 200 on Pro. There is no need to repeat the setup per item, and Temporary uploaded and generated files are processed securely and deleted automatically.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking image gets refused.

Two things to check. First, what the receiving app actually accepts — plenty of upload forms say "images" and mean JPG only. Second, whether the file really is what its name claims: renaming a HEIC to .jpg does not convert anything, and that single mistake is the most common reason a "converted" file is still rejected. Run the real conversion and the extension will match the contents.

ICO Converter supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Premium supports batches of up to 60 files, with the applicable plan limits shown before processing.

No — ICO Converter runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.

The converter fits the whole picture inside each square size and leaves the rest transparent, so a wide or tall image gets empty bands. Crop the image to a square first if you want the icon filled edge to edge.

The largest size is 256×256, and the Embedded sizes list stops there. If you need a larger version of the same logo, keep it as a PNG instead of an icon file.

Each selected size is stored as a PNG image inside the standard ICO container, with its directory header, so the file carries real transparency at every size. Windows and browsers read the container and choose the size they need.

The saved file's name is based on your source image, so rename it to favicon.ico if your site expects that name. Upload it to the site root, or point a link tag in the page head at whatever name you chose.
